What is the best method for applying baseboard caulking to ensure a seamless and professional finish?

The best method for applying baseboard caulking for a seamless and professional finish is to first clean the area thoroughly, then apply the caulk in a steady and even bead along the baseboard joint. Use a caulking tool or your finger to smooth out the caulk and remove any excess. Allow the caulk to dry completely before painting over it for a polished look.
